What’s interesting is that the Edge was to have a 4.5-inch display. The current iPhone 5s has a 4-inch display that is more elongated than the more traditional proportions of what would have been the Edge’s screen.

Apple is expected by some to offer an iPhone later this year with a screen between 4.5- and 4.7 inches, although that display is not expected to use sapphire; instead, it would use Corning’s Gorilla Glass like the current iPhone does.
